Title: Ground-water level lowering method and its equipment
Inventor: NAKAJIMA MAKOTO
IPC: E02D3/10
Filed: 2000-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a ground-water level lowering method with which ground- water level can be lowered efficiently with few collecting and draining facilities when excavation of a deeper area than the ground water level is required, or the area that needs to be lowered is vast, and with which level of ground- water can be lowered where there are obstacles on the surface of the earth. SOLUTION: The lowering of ground-water level is performed by sucking the ground-water with pumps at an edge of a pipe which is protruded on the surface of the earth while one or multiple pipes equipped with collecting parts are inserted horizontally along the ground-water area, and collecting parts are located in the ground-water area. Preferably, multiple pipes should be inserted so that the collecting parts of the pipes inserted into the ground water area can shift toward the axes of the pipes. The lowering the level can be performed efficiently with the minimum number of pipes by inserting multiple pipes into the ground-water area along the area that needs to be lowered like the pipes are surrounding the area even if the area is vast.

Title: Beam splitter structure group and interferometer with it
Inventor: SPANNER ERWIN
IPC: G02B5/04
Filed: 2000-02-24
Abstract: PROBLEM TO BE SOLVED: To retain two emission luminous fluxes in parallel each other and at an equal interval even in the case of non-optimum incidence luminous flux by forming the beam splitter element of a beam splitter structure group and a compensation element as a parallel plane plate. SOLUTION: Incidence luminous flux S that is supplied from a HeNe laser reaches a beam splitter element 1 with two boundary surfaces 1.1 and 1.2. After the incidence luminous flux S passes a plate, it hits against a boundary surface 1.2 that is set as a beam splitter surface 1.3 and is divided into partial luminous flux SR and ST. The partial flux SR is transmitted in the direction of a compensation element 2 and is reflected in the direction of the boundary surface 1.2 by a reflection mirror surface 1.4 and becomes emission luminous flux SA1. The partial luminous flux ST reaches a boundary surface 2.1 of the compensation element 2, is refracted by the boundary surface 2.1, and is passed up to a boundary surface 2.2 and becomes emission luminous flux SA2.  The compensation element is formed as a parallel plane plate and ensures that the emission luminous flux SA1 and SA2 are returned to corresponding elements 1 and 2 with an essentially equal optical path length finally.
